The IOI Scientific Committee (ISC) is charged with overseeing the competitions at the IOI. The IOI Scientific Committee (ISC) was established at the GA Meeting on October 14, 1999, at IOI'99 in Antalya-Belek, Turkey.

The International Technical Committee (ITC), a long-term standing committee, works with each Host Country to ensure continuity and quality control of the IOI competition environment (hardware and software).

The ITC oversees the technical side of the contest: program development tools, evaluation software, hardware, networks and their security. It aims to monitor the advances in these fields, collect information relevant to the competition and develop new software if the available one is insufficient. It provides advice in technical matters to the IOI Scientific Committee and to the organizers of the present and future IOI's.
